COMPUTING-SCALE.

SPECIFICATION forming part of Letters Patent No. 735,273, dated August4, 1903. Application Sled September 3, 1902. Serial No. 121,984. (Nomodeld To @ZZ whom t may concern:

Be it known th at LHENEY FRANCIS KINSER, a citizen of the United States,residing at Athens, in the county of McMinn and State of Tennessee, haveinvented a new and useful ComputingScale, of which the following is aspecification.

The invention relates to improvements in computing-scales.

The object of the present invention is to improve the construction ofcomputing-scales and to provide a simple and comparatively inexpensiveone capable of accurately indicating the value of the goods weighed andadapted to be readily operated to enable the weight of a quantity ofgoods to be ascertained. y

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a side elevation of a computing-scaleconstructed inaccordance with this invention. Fig. 2 is a longitudinalsectional view. Fig. 3 is a vertical sectional view on the line 3 3 ofFig. 2.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

l designatesasupporting-frame designed to be connected with the base orframe (not shown) which receives the platform for the reception of thegoods to be weighed; but the weighing mechanism, hereinafter described,may be connected with any other form of receptacle for the goods to beweighed. The frame 1, which is provided with an open-top portion 2,hasoutwardly-extending arms 3 and 4, supporting a fixed horizontal bar 5,which extends from one end of the frame to the other and which forms asupport for a sliding price-block G, hereinafter described. Fulcru medwithin the open portion 2 is a beam 7, having knife-edge bearings 8 andpreferably suspended by short vertical links or plates 9, which are alsoprovided with knife-edge bearings 10. The beam 7 is provided at itslefthand arm with knife-edge pivots 11 and is 5o connected thereat by alink or rod 12 with the platform-levers. (Not shown.) The rod 12 isprovided at its Lipper end with an eye, which is linked into anapproximately U-shaped link having hooks or eyes at its sides to receivetheknife-edge pivots 11. The knifeedge pivots 11 may be constructed inany desired manner and may consist of a pin set in an opening of thebeam and projecting from opposite sides thereof. The right-hand end ofthe beam 7 is provided with knife-edge pivots receiving uprightsupporting bars or links 13, arranged at opposite sides of the xedhorizontal bar 5 and connected with the same and with the frame 1 byupper and lower horizontal links l1 and 15, which are adapted tomaintain the plates or links 13 in an upright position and permit thesame to move vertically. The upper ends of the plates or links supportacalculator or computing beam 16, composed of upper and lower barsconnected at their ends. The calculator or computing beam is suspendedby knife-edge pivots 17, which are arranged in openings of short links18, and the latter are pivoted at their upper ends to the uprightsupporting plates or links and are adapted to permit a limited play ofthe calculator or computing beam to prevent friction.

The weight of the platform and the lefthand arm Vof the beam '7 isadapted to counterbalance the calculator or computing beam and itsconnections when the weights of the calculator-beam are at zero, and thesaid beam 7 is provided at its left-hand end with an adjustable weight19, adapted to correct any inaccuracy of the scale and bring the partsto a poising-point when the said weights are at zero.

The slidable price-block 6 is provided with an opening 2O to receive thebar 5, and it has an upwardlyextending slotted arm 21,` in which ismounted a fulcrum 22, having knifeedge bearings and adapted to engagethe upper edge of the lower bar Aof the calculator 0r computing beam,which is provided with notches 23 to receive the said fulcrum 22. Thearms of the lower bar are provided with three sets of graduations, andthe upper bar of the calculator or computing beam is similarlygraduated. These graduations are designed to be provided for'use'asfollows: The bottom graduations, which may be arranged IOO Y than thirtycents.

for weighing goods at a price less than three cents a pound, arelpreferably employed for ascertaining the weight in simple weighingoperations when the price-block is located at the inner end of thegraduations at one cent per pound. The top graduations are preferablyarranged for weighing goods at a price between three cents and' thirtycents, and the intermediate graduations are preferably arranged forweighing goods at a price greater The graduations,however, may be of anyother desired character to suit the use to which the scale is to beapplied. The right-hand arm of the lower bar of the calculator orcomputing beam is provided vwith a slidable poise or Weight 24, and theupper bar has weights or poises 25 and 26. The poise 25 is a tare poiseor weight and is adapted to counterbalance a vessel or other receptaclefor the goods to be weighed, and the other poise 26 operates on thegraduated portion of the upper bar of the calculator or computing beam.The calculator or com puting beam is provided at its right-hand end withan eye 27, which is linked into a keeper or guide 28, located at theupper end of the arm 4L, which extends above the fixed bar 5.

The scale is operated by iirst moving the priceblock to the price perpound of the goods to be weighed, and if a vessel is to be used it iscounter-balanced by the tare poise 25. The poises 24 and 26 are then setto indicate the price of the goods, and a sufficient quantity of thesame is placed on the scale to bring the latter to a poisiug-point. Whenit is desired to ascertain the price of a quantity of goods, theprice-block is arranged to indicate the price per pound. The goods arethen placed upon the scale and the poises 24: and 26 are adjusted tobring the scale to a poising-po-int, and it will indicate the price ofthe goods.

What I claim is- I. In a scale of the class described the combination ofa frame, a movable price-block mounted on the frame, a lower beamfulcrumed on the frame at a point below the price-block and designed tobe connected with the goods to be weighed, an upright supporting devicepivotally mounted on the lower beam and extending upward therefrom,means for maintaining the supporting device in an upright position, acalculator-beam pivotally connected with the upright supporting deviceand located above that portion of the frame on which the price-block ismounted and arranged to be fulcrumed on the said price-block, and amovable poise for the calculator-beam, substantially as described.

2. In a scale of the class described, the combination of a frame, alower beam fulcrumed on the frame and designed to be connected with thegoods to be weighed, a supporting device pivotally supported by andextending upward from the lower beam, a horizontal link pivotallyconnected with the supporting device and with the frame to maintain theformer in an upright position, a calculatorbeam pivotally connected withthe supporting device and having a movable poise, and a price-blockmounted on the frame, substantially as described.

3. In a scale of the class described, the combination of a frame, alower beam fnlcrumed between its ends on the frame and designed to beconnected with the goods to be weighed, an upright support pivotallymounted on the lower beam and extending upward therefrom, acalculator-beam pivotally connected with the support and having movablepoises, upper and lower oscillatory links arranged horizontally andconnecting the support with the frame, and a slidable price-blockmounted on the frame and arranged to engage the calculator-beam,substantially as described.

. 4. In a scale of the class described, the combination of a framehaving a fixed horizontal bar, a lower beam fulcrumed on the frame, anupright pair of supporting-plates located at opposite sides of the fixedhorizontal bar and pivotally connected at their lower ends with thelower beam, a calculator-beam arranged between and pivotally connectedwith the supporting-plates, horizontal links connecting thesupporting-plates with the frame, a price-block movably mounted on thehorizontal bar and arranged to form a fulcrum for the calculator-beam,and a movable poise arranged on the calculator-beam, substantially asdescribed.

5. In a scale of the class described, the combination of a frame havingan open-top portion and provided with a fixed horizontal bar, ahorizontal beam located within the top portion of theft-ame and providedat one end with an adjustable weight, short links suspending the saidbeam from the frame and arranged between the ends of the former, a pairof upright plates located at the other end of the 4 said beam andpivotally connected therewith and arranged at opposite sides of thehorizontal bar, a calculator-beam, a pair of short links suspending thecalculator-beam from the upper ends of the upright plates, upper andlower horizontal links connecting the upright plates with the frame, apriceblock mounted on the frame and arranged to be engaged by thecalculator-beam, and a movable poise mounted on thelatter, substantiallyas described.

In testimony that I claim the foregoing as my own I have hereto-affixedmy signature in the presence of two witnesses.
